[03:06] <guruprasad> ernstp, the publisher should be unstuck now. If you are still noticing issues, please report them to us on #launchpad.
[07:33] <guruprasad> cjwatson, I fixed the broken publisher (the lp-signing production deployment didn't actually deploy the expected build label till we fixed it) and now the noble suite of your PPA is now dual-signed with its old key and a shiny, new 4096-bit RSA key! 🎉 Thanks again for your help!
[08:48] <cjwatson> guruprasad: Thanks!  The "Technical details about this PPA" section on https://launchpad.net/~cjwatson/+archive/ubuntu/ppa still shows only a 1024-bit key though.
[08:57] <guruprasad> cjwatson, that is expected. The plan is to fully (but incrementally) re-sign all the affected archives and then replace the 1024-bit RSA key in the visible places (UI, API etc.) with the new 4096-bit RSA key so that there is a way to do a smooth transition.
[08:57] <cjwatson> ok
[08:58] <guruprasad> apt, ubuntu-software-properties-common etc. will take care of handling the migration on the client-side from 24.04.1 onwards.
